The massive storm that paralyzed the East Coast this weekend left behind mounds of snow, happy sledders and frustrating travel delays. Here's a look at what's moving and what isn't.

Airports in New York and New Jersey — LaGuardia, John J. Kennedy and Newark Liberty — were open, but only a limited number of fights were expected Sunday, according to the Port Authority of New York and New Jersey. LaGuardia had 693 cancellations, while Newark Liberty had 597.

AirTrain JFK and AirTrain Newark were both temporarily suspended, replaced with bus service.

Flights throughout the country continue to be canceled. More than 3,500 were scrapped Sunday, with another 1,154 delayed, according to online flight tracking service FlightAware. Additional cancellations were expected for Monday.

In all, more than 12,000 flights were canceled after the storm began Friday, as states from North Carolina to New England struggled to clear the snow.

A ban on driving was lifted Sunday as expected for New York City and Long Island, and bridges and tunnels to New York City reopened. Metropolitan Transportation Authority buses resumed their routes, while service on subways and commuter railroads — New Jersey Transit, Metro-North Railroad in New York and Connecticut and Long Island Rail Road — was being restored throughout the day. Alternate side of the street parking regulations were suspended for the week.

The Long Island Rail Road was especially hard hit, with many of its yards buried under more than 2 feet of snow and stalled trains blocking tracks. Seven of its 12 branches would be fully operational by 5 a.m. Monday, the Port Authority said.

Officials at the Washington, D.C., Metro plan to restore limited service Monday. Meanwhile, the Metro extended free parking at its garages until Tuesday. Buses were resuming service as conditions on the roads improved.

In Maryland, where some western parts of the state received up to 3 feet of snow, Gov. Larry Hogan warned residents that driving was still treacherous and he urged anyone who could stay home to keep off the roads. Digging out will several days at least, he cautioned.

Runways at Reagan National and Dulles International airports near Washington, D.C., were closed Sunday for snow removal. Baltimore-Washington International Airport was expecting to resume service gradually over the next 24 hours, officials tweeted on Sunday.

In Philadelphia, all of SEPTA Regional Rail service remained suspended on Sunday. Service was expected to resume with delays Monday morning.

The city's trolleys were operational and bus service was returning on a route-to-route basis.

Philadelphia International Airport was expected to resume its operations gradually on Sunday, it said in a statement. A number of airlines were planning to reduce their schedule of arrivals and departures.

A section of the Pennsylvania Turnpike were hundreds of vehicles were stranded during the storm reopened on Sunday, state officials said.

Amtrak was running a modified service along the Northeast Corridor.

At Boston's Logan Airport, most of the flights affected on Sunday — nearly 150 flights canceled and another 76 delayed — were to and from airports in Washington, D.C., New York City and Philadelphia, the AP reported, citing Massport, the state's port authority.
